Support of nullability was introduced in PHP 7.1 and helps to avoid omitting type declaration or providing default null value for the function parameter for cases when you really want to pass or return null. This build brings the support of nullability in “Extract Interface” and “Change Signature” refactorings. This build delivers new features, bug fixes, and improvements for PHP and the Web, and includes the latest improvements in IntelliJ Platform.

Or, if you have the previous PhpStorm 2017.3 EAP build (173.2290.12) installed, you should soon get a notification in the IDE about a patch update.

The new PhpStorm 2017.3 EAP build (173.2463.17) is now available! You can download it here or via JetBrains Toolbox App.
